OPTIMAL CONDITIONS FOR THE USE OF CORRESPONDENCE-ANALYSIS FOR ELEMENTDETERMINATION IN EELS IMAGES

Correspondence analysis is used for the determination of element local ization and element concentration in electron energy-loss imaging. The introduction of a new method for the quantification of element concen tration embedded in the protocols of correspondence analysis may be re garded as a useful replacement of the power-law estimation technique, especially in regions of the spectrum where the latter method cannot b e used. Conditions for the optimum use of the method are established.
